Lead Full Stack Engineer

Lead Full Stack Engineer to own and evolve the core architecture of the company across both the frontend and backend, and to set the technical bar for how the rest of the engineering team builds full-stack features. You will work directly with the founders on systems that orchestrate real operational workflows across emails, documents, humans, databases, and ERP systems.

What you'll do

• Design, build, and evolve production-grade full-stack applications using Python (FastAPI) and React (Next.js).
• Architect and develop next-generation interfaces for our Systems of Action, enabling seamless human-in-the-loop interactions and complex data visualization.
• Build durable backend workflow systems using tools like Temporal to support asynchronous AI agent execution.
• Improve reliability, observability, and operational tooling across both client and server applications.
• Integrate with enterprise systems such as ERP platforms (SAP, Dynamics, etc.) and external APIs, surfacing that data intuitively on the frontend.
• Scale multi-tenant systems, database architectures (PostgreSQL), and platform abstractions.
• Work closely with product and forward-deployed engineering teams to translate real customer problems into cohesive end-to-end features.

What you'll need

• Strong full-stack engineering fundamentals and production experience owning end-to-end feature delivery.
• Deep experience with React and modern frontend ecosystems, coupled with a strong eye for user experience and interface design.
• Deep experience with Python and distributed / backend systems.
• A strong ownership mentality and systems thinking - you care just as much about UI state management as you do about backend database query optimization.
• Ability to design reliable, observable, maintainable systems.
• Comfort operating in ambiguous, fast-moving startup environments.
• Clear communication and sound engineering judgment.
• Excitement about AI-native software development and agentic systems.
